To all whom it may concern:

Be it known that I, CHARLES F. BROWN, a citizen of the United States, residing at New York, inthe county of N ew York and State of New York, have invented certain new and useful Improvements in Liquid- Measuring Apparatus, and I vhereby de- Glare that the following is 'a full, clear, and exact description thereof, reference being had to the` accompanying drawings, which form part of this specification.

This invention is a novel apparatus for dispensing liquids, and i`s particularly designed for use in dispensing charged Abeveragessuchas beer. l s

The object of the invention is to enable rately measured as. it is dispensed and to avoid loss orl erroneous measure due 'to expansi'on or foaming 'of the liquid when relievedl from pressure. The apparatus is to be interposed between the dispensing faucet 'and the original cask or container, and the liquid is passed through such apparatus as it is dispensed, and is accurately measured thereby and does .not have an opportunity to foam or expand in passing from the original l'container to and ythrou'gh'th'e measuring apparatus. The liquid is measured in stated quantities, and such quantities may lbe registered, so that by inspection ofthe register the owner of the apparatus can at once tell how much liquid has beendispensed; and he can by noting the register readings determine how much liquid has been supplied to him inthe original container. v l will explain one practical form of the invention which will enable those skilled in the art to constructand usefthe same, and refer to the claims for a .sunnnary-of the 'features and combinations of parts vfor which protection is desired; the apparatus however is'I susceptible *of modification in form and arrangementy aswiil be .obvious when the invention is UlIyHnHerStOOd.

.ln said drawingstFigure f1 'isf an end elevation of a `measuringapparatus embodying the invepmticrn. `vFig. Qfis a diagrammatic *sectional view'of such apparatus I The. measuring ,device :proper referafbly consists of a vessel "1,1%Wliich isshown asa l"hd`1iseproiidsniiwith' a port communicating vwith a nipple 1, and head l Valternately with a port communicating with a nipple 1d, to whichnipples are ,attached pipes 2, 2b, hereinafter referred to. Within this cylmder is fitted a piston le which is movable longltudinally of the, cylinder and is adapted to be moved -by the liquidadmitted into the cylinder as 'hereinafter explained.

T-he pipes@l and 2b are respectively con-l nected at their outer ends -to\ports 2, 2d, of a four-Way valve casing 2, said ports 2a, 2' being preferably diametrically opposite each other. .Intermediate the ports 2, 2d are preferably diametrically opposite ports 2", 2f; the port 2? communicates with a supply pipe4, and'fthe port 2f with a dispensing pipe 6, hereinafter Freferred to.

Within the valve casing 2 is a valve 2h to the stem 2 of which is connected a lever 21 by which the valve can be manually operated. This valve has two transverse ports Q, 2k which are soV formed that by turning` neously port Q will establish communication between the ports' 2d and 2f as illustrated in full Vlines in Fig. 4. By turning the valve, ports 2 and 2k .can be 'shifted so that port 2 will establish communication between the ports @and 2f, and port 2k lwill establish communication between the ports 2 and -2'1 as indicated in 'dotted lines in Figli.

The pipe 4 connects with the .liquid Supply. Preferably it communicates with a supply valve 4:- which -inay be connectedfby a pipe j4b.-to a vessel K containing the lijquid to lbe dispensed. Preferably the valve @has two'inlet ports so that it can'be simultaneously lcdnneetedby pipes 4b, 4 to Etwo vesselsvK, TK', and 'by Aproperly ys'hifti't'ng valve 4 commuieation can beI established betweenthe pipe 4 andl either vessel K or K?. f j f" l,

The pipemay leefcoiinecbd 7'to any suitable receiver '13; and? is 4rim'wn as connectedj'to -a VJdisp@heling V"faucet f6? which "can be vopiel'ri atedmanualiy byafhandle All the pipes and parte exposedto contactwitii 'the liquid 'shouldbe made "or lined withinpn-corroding metal. A v

l of' va'lve 2h may be yconnectedto a registering mechanism, 'indicated at 8, which is shifted at'each's'hift of the'valve Jlever to y Vregister the amount of liquid from.

vThe particular registering mechanism which I prefer 'to use forms the subjectmatter of a companion application Serial No. 807,911 filed December 20, 1913, of which this application 'is a division, and such registering mechanism needs no detailed description herein.

In practice the measuring vessel 1 is preferably placed within a cooler or ice boX so that the liquid contents thereof will be chilled.

The operation of the apparatus is as folylows: After the containers K, K have been connected to the casing of the valve 4a, the' latter is opened, and assuming the valve to bein the position shown in Fig. 2, when the faucet 6a is opened liquid will iow from the container K v.through valve 4, pipe 4, port 21, pipe 2 and through the head l of the measuring vessel 1, and the liquid will force the piston 1e in said container to the head 1b thereof, and any liquid contained between the piston 1e and the head 1h will be discharged through the pipe 2", port 2k, pipe 6 and the faucet 6a When the piston 1e has moved against'the head 1b it closes the outlet aperture in said, head and no more liquid escape through the faucet, and no more liquid `can enter the measuring vessel 1. This vessel is made of such size that it will contain a predetermined quantity of liquid, say one pint or one quart, and `the introduction of such a quantity of liquid into-the cylinder will force the piston yto one end thereof. When no more liquid escapes through. the pipe 6, valve 2h may be shifted so as to establish. communication between pipes 4 and 2b, and between pipes2EL and 6 (as indicated in dottedVlines in Fig. 2;)

thereupon, when the faucet 6a is opened,

liquid will flow .from vthe supply through.

pipe 4 and 2"y into the cylinder 1 through head 1b and force the piston 1 to the left; and liquid will be discharged through the pipes 2 and pipe-6 until the piston reaches the head l? of the vessel, then no more liquid will escape through pipe 6,' when the faucet is open, until the valve 211 is again shifted to the position shown in fulllines in Fig. 2. Thus by shifting the valve 2h communica- `tion is established alternately between the supply and the opposite ends of the vessel 1, and between the opposite ends of said vessel and the faucet; but at no timecan direct\ communication be established between the supply and the faucet; 'and the liquid is thus always held undery its initial pressure between the supply and the piston le; luid does not have any opportunity to foam until it is discharged from the faucet. Each shifting movement of the valve 2h may be recorded on the register as described, and at any time by inspecting the register the total amount that has been withdrawn .can be determined.

It is sometimes desirable to cleanse the pipes and passages through which the uid passes, by forcing a chemical solution therethrough. The solution could be passed through the apparatus in the same way that the fluid passes; but it is unnecessary to cleanse the measuring vessel frequently for the reason that it is ke t clean by thereciprocatory movement of t e plunger 13 therein. In order to facilitate cleansing the pipes and valves without running the fluid through the measuring vessel, a by-passpipe 7 may be connected to and between three-way valves 7a, interposed between the pipes 2a and 2b and A the nip les 1" and 1d respectively. These valves 'il when in normal position do not communicate with the pipe 7 but establish communication between ,the pipes 2, 2b and nipples 1, 1d respectively, as shown in Fig. 2. vWhen it is desired to cleanse the circulating pipes without introducing the cleansing solution into the measuring vessel, they valves 7a are turned so as to close communication between pipes 2a and 2b and the cylinder l; and establish communication between the pipes 2a, 2b and pipe 7 then the solution can be circulated through the pipes 4, 2, 7, 2b, and 6, and such pipes` and valves are quickly and thoroughly cleansedf What I claim is: v

1. In a liquid dispensing apparatus'the combination of a measuring vessel provided with openings land an interposed movable memberf pipes connected with said vessel, and means for alternately connecting one of said pipes with a liquid supply and the other with a discharge; with a by-pass connecting the said pipes adjacent the vessel, and means for closing communication between said pipes and the vessel intermediate the by-pass and the vessel and establishing communication between said pipes through the by-pass, or cutting out the by-p'ass pipe and reestablishing communication between said pipes and the measuring vessel.

. 2. In combination, a measuring vessel, a

yreciprocating piston therein,l a four-way `valve casing, pipes connected with opposite between the other end of the Vessel and the dispensing pipe; with a bypass pipe connected with the pipes communicating with the Vessel at points adjacent the Vessel, and

5 valves at the junctions of said by-pass and pipes whereby communication between said pipes and vessel may be closed and communication between said pipes throughthe bypass pipe established, or whereby communi- 10 cation between the by-pass and said pipes -vesseL In testimony that I claim the foregoing as my own,1 aiix my signature in presence 15 of two witnesses.
